ArborPGR - Paclobutrazol Plant Growth Regulator for Trees & Turf
ArborPGR 22.9 SC is a paclobutrazol-based plant growth regulator designed for use on trees
and non-residential turfgrass. Applied as a soil drench or soil injection, ArborPGR 22.9 SC
slows excessive vegetative growth while promoting deeper green color, improved root
development, drought tolerance, and overall plant vigor. In turfgrass, it helps reduce mowing
frequency and improve density and appearance.

Key Benefits
Slows excessive vegetative growth
Promotes deeper green color and improved plant appearance
Enhances root development and stress tolerance
Reduces mowing frequency on labeled turfgrass
Xylem-mobile formulation for long-lasting results
Ideal for utility, municipal, arboricultural, and landscape use

Application Methods
Flexible application options including foliar spray, basal drench, or soil injection depending on
site conditions and target plant material
Apply near the root zone or soil interface for optimal uptake and consistent growth regulation
response
Water-in recommended after turf applications to move active ingredient into the soil and improve
absorption while minimizing runoff

Targets / Uses
Tree growth management, utility line clearance reduction, drought stress management, turfgrass
growth regulation, and improved turf density and color
